TAKE-OUT DEVICE FOR BOTTLE-BLOWING MACHINES.

Application filed Ital-ch 2, 1922. Serial No. 540,588.

To all whom, z'tvnay concern:

Be it known that JAMES W. LYNCH, a citizen of the United States, and resident of Alexandria, county of Madison, State of Indiana, has invented an Improvement in Take-Out .Devices for Bottle-Blowing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention aims to provide an improved automatic means for transferring or removing the finished or partly finished ar ticles from the molds of automatic or semiautomatic glass-blowing machines, for'example of the type as shown in ap icatien Serial No. 172,678, filed June 4, 191%, by me jointly with Edward G. Bridges.

The subject matter claimed therein is taken from the abovementioned application, with respect to which subject matter I am the sole Inventor.

In the accompanying drawings, wherein I have shown one embodiment of the invention.

for purposes of illustration, Fig. 1 is a diagrammatic view, partly in side elevation and partly in cross-section, of a portion of a glass blowing machine, showing the take-out device in its normal position ready to grasp and remove a finished article from the mold;

Fig. 2 is a plan view of the take-out device and portion of the mold table and conveyor; and

Fig. 3 is an enlarged view, partly in cross-- section of the take-out device, showing it wit-h an article in raised position ready to be deposited on the conveyor.

In the particular embodiment of my invention selected for illustration herein and shown in the drawings, referring to Fig. 1, the ware is finished by blowing in separable molds 10, attached to a rotatabletable 11,

provided with suitable means, preferably operated by compressed air, for rotating it intermittently in synchronism with the other parts of the machine, as for example, shown and described in said application Serial No. 172,678. A conveyor 12 is also provided for removing the ware from the machine though the device is not restricted to use with a conveyor.

The take-out device for transferring the ware from the molds to the conveyor or swung together.

other receiving means comprises a carrier 13 slidable on a rod 14 and moved back and forth b means of a iston 15 in a c linder 16 on t e frame of t e machine. T e carrier 13 has depending from it two lugs 17 between which grippers 18 are loosely supported on a pm 19 which is movable up and down 1n alining slots 20 in the lugs. The grippers are crossed on the pin 19 and have on the1r outer or lower ends fingers 21 which are shaped to grasp the neck of the bottle or other ware when the grippers are actuated.'

The upper ends of the grippers are loosely secured to a yoke 22 by pins 23 sliding in slots 24 in the grippers, so that when the yoke 1s ralsed by means of a piston 25 on its upper end which works in a cylinder 26 in the carrier the lower ends of the grippers are I The yoke 22 has a slot 27 m its lower end to embrace the pin 19 so It may have some vertical movement before it raises the pin. A spring pressed 7 plunger 28 slidable in an axial hole in the yoke normally holds the pin 19 in its lowermost position in the slots 20.

Freferably as the molds containing finished ware are opened as they approach the position of the take-out devlce by suitable means, such as the cam 29 which engages a roller upon the yoke 30 to which the mold closing links 31 are secured, as shown in Fig. 2, leaving the ware standing on the $5 mold bottom 32 and with its neck in osition to be grasped by the fingers 21 o the take-out device.

Compressed air for operating the take-out to remove the ware is supplied through the main 33, in which in the illustrative device the pressure is on whenever the table is stationary and is cut off automatically before the table starts to rotate.

When the air comes on in the main 33 the yoke 22 is raised by the piston 25, and the grippers are first swung together to grasp the ware. When they can swlng no closer together because either they are stopped by the ware between them or the pin 19 is'engaged by the bottom of the slot 27 in the yoke, further movement of the yoke lifts them bodily, together with the ware, until the piston 25 reaches the top of itsstroke and uncovers the port 34 in the side wall of the cylinder 26 and admits air through the hollow piston rod 35 to the cylinder 16, whereupon the piston 15 is moved to slide the carrier l3 and its load away from the table 11 and over the conveyor 12, where it is preferably held suspended until just before the table starts to rotate.

Preferably the pressure in the main 33 is cut off immediately before the movement of the table and compressed air is admitted to the main 36 and to the top of the cylinder 26, thereby forcing down the piston 25 and lowering the yoke 22 and grippers untll the pin 19 strikes the lower end of the slots 20, whereupon further lowering of the yoke swings the grippers apart and releases the ware to be carried away on the conveyor 12. The speed of movement of the piston 25 may be controlled by suitable valves 37 in the connections from the mains to the cylinder 26.

The conveyor is moved intermittently 1n synchronism with the table by a ratchet 38 or other suitable mechanism operated in forward direction by air pressure from the main 33 and in reverse direction by air pressure from the main 36 acting on a piston 39 in a cylinder 40. The speed of operation of the conveyor may be controlled by a suitable valve 41 in the pipe connecting the main 33 with the cylinder 40.

The return movement of the carrier 13 is effected in the illustrative device after the table has rotated part way by means of a cam 42 on the table which operates a valve 43 in an air pipe 44 connected to the pressure main 86 and leading to the outer end of the cylinder 16. This valve is normally held closed by a spring or other suitable means, in which position the pipe 44 is open to the atmosphere through the valve groove and port 45 (shown in dotted lines in D The exhaust air from the inner end of the cylinder 16 passes through the hollow piston rods around the groove 46 in the piston 25 and escapes through the port 47 in the side wall of the cylinder 26. Thus the piston 25 operates as a valve for the carrier moving cylinder 16.

The table turning mechanism and valves for controlling the admission of air to the mains 33 and 36 are not shown as such devices are in common use and well understood by persons skilled in the art.

My invention obviously is not restricted to the particular embodiment thereof herein illustrated and described, nor to the particular purpose stated. For example, a similar device may be utilized for transferring a partly finished article from one mold to another.

In the claims the words ware or article are used to designate the partly finished blank or parison as well as the finished bottle or jar.
